Study on Top Slice Irregular Destroyed Areas of Spatial Exploration Location and Mining Method

Abstract

Slice mining, when mining lower slice need to consider on the effect of current face from top slice, especially when on top slice mining space irregular, it will make mining more difficult. Hair is drainage of these characteristics the lao keng kou mine by Geophysical means, take advantage of the characteristics of the water content in the mined-out area and media mutation specific master distribution of the residual top delamination, geophysical no damage proved an effective means of underground space structure and highly targeted research stoping methods, based on the conclusions formulated to ensure the safety and production measures in place to provide the necessary reference.
